In the title compound, C(13)H(10)Cl(3)NO(2)S, the N-C bond in the C-SO(2)-NH-C segment forms trans and gauche torsion angles with respect to the S=O bonds. Further, the N-H bond in the C-SO(2)-NH-C segment is anti to the meta-Cl atom in the anilino benzene ring and nearly syn with respect to the ortho-methyl group in the sulfonyl benzene ring. The C-SO(2)-NH-C torsion angle is -49.4 (2)°. The sulfonyl and aniline benzene rings are tilted relative to each other by 54.6 (1)°. In the crystal, mol-ecules are linked into chains along the c-axis direction by inter-molecular N-H⋯O hydrogen bonds.
在标题化合物C₁₃H₁₀Cl₃NO₂S中，C-SO₂-NH-C片段中的N-C键相对于S=O键形成反式和顺式扭转角。此外，C-SO₂-NH-C片段中的N-H键与苯胺苯环中的间位氯原子呈反式，与磺酰苯环中的邻位甲基几乎呈顺式。C-SO₂-NH-C扭转角为-49.4 (2)°。磺酰苯环和苯胺苯环彼此倾斜54.6 (1)°。在晶体中，分子通过分子间N-H⋯O氢键沿c轴方向连接成链。
